I recently acquired a new-old-stock Sun Type 6 keyboard & mouse set with the proprietary DIN interface. (The Type 6 was also available in USB.) I already have older Type 4 and 5 sets (which were only ever available with the proprietary interface) and a Type 7 (which was USB-only). All, including the new Type 6, are the UNIX layout with Caps-Lock and CTRL keys reversed (among other changes). I've seen used, bare Type 6 keyboards in less-than-stellar condition with asking prices the same or higher than my NOS set.
It included all the accessories: a keyboard wrist rest, two CDs, a Sun power cord, a mouse pad, and even the 25-pin serial port breakout cable. I've been looking for one of those for years for my SparcStation 20s. I don't actually need dual serial ports on any of them, and it's straightforward to wire your own (if I'd ever gotten around to it), but I'm quite happy to have that little trinket added to my collection.
It's little stuff, but I'm oddly excited by it all!
